Drug Development.

Background: Global epidemiological studies involving over nine million participants have shown a 35% lower incidence of Alzheimer's Disease (AD) in older cancer survivors compared to those without a history of cancer. This inverse relationship, consistent across recent studies with methodological controls, suggests that cancer itself, rather than cancer treatments, may offer protective factors against AD. This insight opens avenues for novel therapeutic strategies targeting early AD by harnessing cancer-associated protective factors.

Evaluation of the Patient Global Impression of Symptom Severity (PGISS) Score as a Subjective and Objective Measure of Disease Activity in Chronic Rhinosinusitis.

Background: The Sino-nasal Outcome Test (SNOT-22) is a 22-question survey that is utilized to evaluate health-related quality of life of patients with chronic rhinosinusitis (CRS). The Patient Global Impression Symptom Severity (PGISS) is a similar yet versatile instrument that combines features of both a Likert scale and a visual analog to assess symptom severity in CRS patients. While previous studies have evaluated the validity of SNOT-22 as an instrument to measure CRS patients' symptom severity, no studies have evaluated PGISS scale's ability to evaluate and guide treatment plans for CRS patients.

Dementia Care Research and Psychosocial Factors.

Background: The dual-cyclical relationship between language and cognition, encapsulated in linguistic relativity, underscores the reciprocal influence of thoughts on communication and vice-versa. This study explores the intricate changes in pragmatics, a fundamental aspect of human communication, during the aging process, considering changes in sensory abilities, cognition, and language.

Method: Sixty participants, aged ≥50 years with a minimum of five years of formal education, were included, excluding those with neurological or psychological illnesses.

"I Aim to Fulfill My Promise": Dementia Caregiving from the Perspective of Spouses and Partners.

In the United States, spouses provide 17% of in-home care for people living with dementia. Negative impacts of dementia care on spouses/partners are well-documented, but we lack information about the holistic experience for spouses/partners. We conducted a secondary thematic analysis of data from two observational studies about everyday music engagement and dementia care at home.

Gut-derived lactic acid enhances tryptophan to 5-hydroxytryptamine in regulation of anxiety via .

The gut microbiota plays a pivotal role in anxiety regulation through pathways involving neurotransmitter production, immune signaling, and metabolic interactions. Among these, gut-derived serotonin (5-hydroxytryptamine, 5-HT), synthesized from tryptophan metabolism, has been identified as a key mediator. However, it remains unclear whether specific microbial factors regulate tryptophan metabolism to influence 5-HT production and anxiety regulation.

Objective: Posterior cervical spine surgery can result in significant discomfort in the post-operative period. Post-operative pain management presents a challenge, particularly in the elderly population which is more sensitive to adverse effects from analgesia. We aimed to compare outcomes after peri-operative posterior cervical muscle plane blocks versus patients who received general anesthesia only.

Epidemiology of Consumer Product-Related Ocular Injuries in the Incarcerated Population.

Purpose: To characterize the epidemiology of consumer product-related ocular injury in the United States (US) incarcerated population, and identify preventable causes.

Methods: The National Electronic Injury Surveillance System (NEISS) database was queried for cases of eye injury from 2014 to 2023. Incarcerated cases were identified using the keywords "prison", "jail", "inmate", and "incarcerate".

Molecular and Functional Significance of Growth Differentiation Factor-15: A Review on Cardiovascular-Kidney-Metabolic Biomarker.

Cardiovascular-kidney-metabolic (CKM) syndrome is the association between obesity, diabetes, CKD (chronic kidney disease), and cardiovascular disease. GDF-15 mainly acts through the GFRAL (Glial cell line-derived neurotrophic factor Family Receptor Alpha-Like) receptor. GDF-15 and GDFRAL complex act mainly through RET co-receptors, further activating Ras and phosphatidylinositol-3-kinase (PI3K)/Akt pathways through downstream signaling.

Prognostic Value of Tumor Regression Grade Combined with Pathological Lymph Node Status in Initially Node-Positive Rectal Cancer Treated with Neoadjuvant Chemoradiotherapy.

Background: The prognostic value of tumor regression grade (TRG) after neoadjuvant chemoradiotherapy for rectal cancer is inconsistent in the literature. Both TRG and post-therapy lymph node (ypN) status could reflect the efficacy of neoadjuvant therapy. Here, we explored whether TRG combined with ypN status could be a prognostic factor for MRI-based lymph node-positive (cN+) rectal cancer following neoadjuvant chemoradiotherapy.

Trends and disparities in cardiovascular disease-related mortality among adults with myeloproliferative neoplasms in USA.

Aims: We aimed to perform a retrospective cohort study using the Centers for Disease Control and Prevention's (CDC's) Wide-Ranging Online Data for Epidemiologic Research (WONDER) database to analyse the trends in cardiovascular disease (CVD)-related mortality in patients with myeloproliferative neoplasms (MPNs) from 1999 to 2020.

Methods And Results: We analysed the death certificate data from the CDC WONDER database from 1999 to 2020 for CVD with co-morbid myeloproliferative disorders in the US population. Age-adjusted mortality rates (AAMRs) and 95% confidence intervals (CIs) were computed per 1 million population by standardizing crude mortality rates to the 2000 US census population.

The Red Cell Distribution Width to Albumin Ratio: A Novel Prognostic Indicator in Hepatitis B Virus-Related Hepatocellular Carcinoma.

The prognostic significance of the red blood cell distribution width to albumin ratio (RAR) spans various diseases, yet its utility as a biomarker for hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) remains unclear. We retrospectively studied 1,413 patients with HBV-HCC. Receiver operating characteristic curves identified optimal RAR cut-offs, stratifying patients into H-RAR and L-RAR groups.

Hyperbaric oxygen therapy attenuates brain radiation-induced cognitive deficits in rats.

Effective therapies for cognitive impairments induced by brain irradiation are currently lacking. This study investigated the therapeutic potential of hyperbaric oxygen therapy (HBOT) for radiation-induced brain injury in a randomized controlled experimental model using adult male Wistar rats. Adult male Wistar rats were divided into four experimental groups: 0 Gy whole brain radiotherapy (WBRT) with normal baric air (NBA) treatment, 0 Gy WBRT with HBOT, 10 Gy WBRT with NBA, and 10 Gy WBRT with HBOT.

Tubulointerstitial nephritis antigen-like 1 promotes the progression of liver fibrosis after HCV eradication with direct-acting antivirals.

Although therapies based on direct-acting antivirals (DAAs) effectively eradicate hepatitis C virus (HCV) in patients, there is still a high risk of liver fibrosis even after a sustained virological response. Therefore, it is of great clinical importance to understand the mechanism of potential factors that promote liver fibrosis after virological cure by treatment with DAAs. Here, we found that tubulointerstitial nephritis antigen-like 1 (TINAGL1) is significantly increased in HCV-infected hepatocytes and in the liver of patients with liver fibrosis, and that higher TINAGL1 expression persists in HCV-eradicated hepatocytes after treatment with DAAs.

Involvement of Tim-3 in Maternal-fetal Tolerance: A Review of Current Understanding.

As the first T cell immunoglobulin mucin (Tim) family member to be identified, Tim-3 is a powerful immune checkpoint that functions in immunoregulation and induction of tolerance. Conventionally, Tim-3 is considered to play a role in adaptive immunity, especially in helper T cell-mediated immune responses. As researches progress, Tim-3 has been detected in a wider range of cell types, modulating cell function through ligand-receptor interactions and other pathways.

Mitochondrial SIRT2-mediated CPT2 deacetylation prevents diabetic cardiomyopathy by impeding cardiac fatty acid oxidation.

Dysregulated energy metabolism, particularly lipid metabolism disorders, has been identified as a key factor in the development of diabetic cardiomyopathy (DCM). Sirtuin 2 (SIRT2) is a deacetylase involved in the regulation of metabolism and cellular energy homeostasis, yet its role in the progression of DCM remains unclear. We observed significantly reduced SIRT2 expression in DCM model mice.

Deficiency of Epithelial PIEZO1 Alleviates Liver Steatosis Induced by High-Fat Diet in Mice.

PIEZO1 has been found to play a vital role in regulating intestinal epithelial cells (IEC) function and maintaining intestinal barrier in recent years. Therefore, IEC PIEZO1 might exert a significant impact on liver metabolism through the gut-liver axis, but there is no research on this topic currently. Classic high-fat diet (HFD) model and mice with IEC-specific deficiency of PIEZO1 ( ) were used to explore the problem.

USP25 stabilizes STAT6 to promote IL-4-induced macrophage M2 polarization and fibrosis.

As a leading cause of morbidity and mortality, fibrosis is the common pathway of various chronic inflammatory diseases in organs and causes death in a large number of patients. It can destroy the structure and function of organs and ultimately lead to organ failure, which is a major cause of disability and death in many diseases. However, the regulatory mechanism of organ fibrosis is not well clear and the lack of effective drugs and treatments, which seriously endangers human health and safety.

Fibroblasts in heterotopic ossification: mechanisms and therapeutic targets.

Heterotopic ossification (HO) refers to the abnormal formation of bone in non-skeletal tissues. Fibroblasts have traditionally been viewed as stationary cells primarily responsible for producing extracellular matrix during tissue repair and fibrosis. However, recent discoveries regarding their plasticity-encompassing roles in inflammation, extracellular matrix remodeling, and osteogenesis-highlight their potential as key contributors to the development of HO.
